To all 'whom it may concern:

Be it known that We, lnnnnnion EL Ben- DEL, a citizen of the UnitedStates, and loma BERGMANN, a. citizen of Germany, both residing in thecity of St. Louis and State of Missouri, have invented a certain new anduseful improvement in Cohe- VenS, of which the following is a tull,clear, and enact description, such as Will enable others slrilleol inthe art to which it oppertains to make and use the saine.

bull: ci

`This invention relates to eolie ovens oi the type in which the chambersthat receive the coal which is to be converted into coke are arran 'edin an inclined position.

v@ne objectionable feature of coke ovens ont the type referred to `thatare now in v`general 'use is that the coal chambers ci saine are of suchforni that when the coai expands or swells, during1 the operation ofdriving oii' the gases, the top Walls of the coal chambers aresubjectecl to abnorniai strains or pressures,l due to the increasevinthe coal contained in the chanibe The main object of our invention is toprovide an inclined. coke oven which is so designed that the top Wailsof the coal chain bers will not be subjected to undue pressure orstrains from the coal in same, during" the operation of converting thecoal into coke.

ylilo this cnil wejhave clevisecl a coke oven equipped with one "or`more inclinei coal chambers, each oiwliicliis provided with top Wallwhich is so designed that the coal in the chamber can eXp-andi or svveliduring n the coking operation, Without causing the coal to exert anabnormal or undue prcssrufc on the walls of the coal chamber.

Anti'anotlier object of our invention is to provide an inclined cokeoven havingm a coal chamber that is provided with means :torpermitting,A the gases to escape therefrom at one or more pointsintermediate the ,ends ont the chamber.

Referring to the drawings, whichillus-j trate the preferred form 'oi3 our inventinni '9 designates thecoal chambers of the oven; which are arranged in an inclinedpositioinz.as shown. in lig. i, cach of said chambers being; provicleol at itsupper end with a fend opening E); through which coal is introduced intothe chamber anci provideci at its lower with a door 3 that normallycloses a c scharge opening' through which the coke is reniovc Jlroro thechamber. The top wall oi each of the coal chambers 9, instead of beingarrange@ parailel with the bottom wali of chamber, as has heretoforebeen the etico in inclined coke ovens, r in such a manner that the coaiin sairi chamber will not Contact with the top Wall ci? the chamberthroughout the entire area otisaicl top Wall when the chami ber ii'ileflwith coal, preparatory to the opera. on of heating the coal toconvert itinto colic., Iilie top Wall of `the coal chaincan be formed various WaysWithout nrting; iroin the spirit ci' our invention, in practice'weprefer to provide the top Waii of the chamber 9 with one or :moreoii'sets G, so to iorin a relief space or spaces above the toti surfaceet thepile of coal in the chamber. lathe forni of our invention hereinshown the portion Bot the top Wall ci@ the chamber 9 adjacent the lowerenel (ii l ai chamber is spaced 'farther away from the bottom of thechamber than tv portion i of saicl top wall adjacent the opper endV ofthe chamber, thus producing the eiiset' ci in the top Wall that forms areiie'f space above the tog surface of the pile oi' coal in the chamber.VVhen the bulk C coa'i in chamber 9 increases, .diie

parisien or snm of the coal, during le colring; opera the relieii spaceor' spaces above the top silrincc of the pile of coal permits the coalto shift sniliciently prevent the top Wall of the chamber 9 rein beine;sabjectecl to undue strains i in other Words, when the` coalcx nels, orswelis, some ci? the coal iviil be- 'orced upwith auxiliary gas outletports 17. In the form of our invention herein shown, in

which the .top wall of each coal chamber is provided with only a singleoffset `6, an auX- iliary gas outlet port 17- isy formed 1n the odsetportion of the top wall, so as to per- Y mit the gases generated in thelower portion of the chamber 9 to escape therefrom freely. The gasesthat are generated in the upper portion 0f the chamber 9 escape there- Cfrom through a conduit 1. If desired, the

auxiliary gas outlet port 17 intermediate the ends ofthe chamber 9 canbe connected with the main gas outlet port at the upper end of saidchamber by means of a gas passageway 5, as shown in Fig. 1.

The coal chambers 9 0f the oven are heated by gas generated 'in a gasproducer located at the rear of the oven, as shown in Fig. 1, andprovided with a fuel chamber 14 to which fuel is supplied through a feedopening 13 at the upper endfof said fuel chamber. Each of the coalchambers 9 of the coke oven is provided at its rear end with a cokedischarge passageway 15 that is inclined downwardly, so that coke canescape through same from the chamber 9 when the door 10 at the lower endof .said passageway is opened, the door 10 being normally closed.` Whenit is desired to supply fuel to the producer, the door 10 of one of thecoal chambers is opened, so as to per mit coke to escape by gravity fromthe chamber and enter a device that conveys or conducts the coke to thefuel feed opening 13 of the gas producer. Any suitable means may be usedfor conveying or conducting the coke from the coke discharge passageway15 to the fuel feed opening 13 of the gas producer, such, for example,as a car 11 that .travels on rails' arranged at the rear side of theoven above the gas producer and provided with a hopper 12 into which thecoke is discharged from the passageway 15 when the door 10 that controlssaid passageway is opened. A single car 11 may be used with a battery ofcoke ovens,`and after the car has been positioned properly with respectto the coal :hamber 9, from which the coke is to be taken, the hopper 12of the car is filled with coke by opening the door 10 of the chamber,the coke passino; from the hopper of the' car into the .fuel opening 13of the gas producer." This feature of the oven forms no part of ourpresent invention, how- .we have herein illustrated said top tails ofconstruction of the oven, other than the shape or form of the top wallof the coal chamber, are immaterial, and that whillt.

provided with only a single offset that forms a relief space above thecoal, said to wall could be provided with a plurality o such offsets, orcould be formed in various ways, without departing from the spirit ofour 1nvention. Furthermore, instead of providing 'the coal chamber withonly a single auxiliary gas outlet port, said chamber could be providedwith a plurality of such ports arranged intermediate the upper and lowerends of the chamber, so as `to permit the gases to escape freely fromdifferent zones or sections of the coal chamber.

Having' thus described our invention, what we claim, and desire tosecure by Letters Patent, is:

1. A coke oven having an inclined coal chamber that is adapted to befilled .with coal, the bottom wall of said chamber being straightorcontinuous and top wall of said chamber' being provided on its innerside with an offset for the purpose described.

2. A coke oven having an inclined coal chamber whose bottom wall isstraight or continuous and whose top wall is rigld and composed ofsections, the inner sides of which are located different distances fromtheA straight-bottom of the chamber.

3. A cokel oven having an inclined coal chamber whose-bottom wall isstraight and whose inner top wall is composed of a plurality of rigidmalalining sections so that when said chamber is lled with coal one ofsaid sections will be spaced away from the upper surface of the ile ofcoal in the chamber, thereby providing a relief space that eliminatesthe liability of said top wall being subjected to undue strains when thebulk of the coal is increased during the coking operation.

4. A coke oven having an inclined coal chamber whose bottom-wall isstraight or continuous and whose top wall is provided on its inner side,intermediate its ends, with an oi'set that connects two portions of saidtop wall whose inner surfaces are located different distances from thebottom of the chamber.

5. A coke oven having an inclined coal chamber Whose bottom wall isstraight and whose top wall is rigid and provided on its inner side withan offset, located intermediete the upper and lower ends of the chamber,and a gas outlet formed in the odset portion of said top Wa'll. e

6. A. 'coke oven having a coal chamber 5 Whose bottom wall lies in a.continuous inclined plane, and whose top wall is composed o a pluralityof sections lying in inelined planes didering from the plane of thebottom wall, and a substantially horizontally-disposed section joiningsaid upper 10 inclined planes so as to form an offset for the purposedescribed.
